^^^^^^^^^^^^^
|
||||
|
||||
This is a simple unit test for the TIFF creation library at apps/graphic/tiff.
|
||||
It is configured to work in the Linux user-mode simulation and has not been
|
||||
tested in any other environment.
|
||||
|
||||
At a miniumum, you would probably have to change the hard-coded pathes to
|
||||
the TIFF files defined in the example to run in an embedded platform.

README for the TIFF Creation Library
|
||||
=====================================
|
||||
|
||||
This directory contains a library that can be used to create TIFF image
|
||||
files. This file was created for the purpose of supporting screen dumps
|
||||
from an LCD. Howeve, the logic is general and could be used for most
|
||||
any purpose.
|
||||
|
||||
The only usage documentation is in the (rather extensive) comments in
|
||||
the file apps/include/tiff.h
|
||||
|
||||
